Modification to the request and response structure of the chat function to adapt to the muEd API standard

simplify the whole repo structure

[Copilot]

Pull request overview

This PR updates the chatbot Lambda to accept/return the muEd API ChatRequest/ChatResponse schema, including message history, user preferences, and educational context.

Changes:

• Switched index.py + src/module.py to validate/consume ChatRequest and return ChatResponse (muEd format).
• Replaced the legacy “question_response_details” prompt parsing with a new src/agent/context.py that formats muEd context + taskProgress into an LLM prompt.
• Refactored/expanded tests to validate muEd request/response structure and added real muEd example payloads for end-to-end coverage.
